Delta beat Wall Street’s top- and bottom-line estimates for the first quarter, but it forecast smaller-than-expected per-share earnings in the current period. Shares of the airline are up more than 12% following the report, extending gains the stock made following oil’s overnight plunge.

As CNBC’s Michael Wayland reports, the Iran war and the subsequent spike in gas prices have yet to dampen demand for used vehicles. Cox said that inventory, meanwhile, fell below 40 days last month — its lowest level so far this year.

But companies like Walmart, Amazon and Target are chipping away at Nexcom’s market share, leading the Navy to embark on an aggressive turnaround plan. CNBC’s Gabrielle Fonrouge and Ryan Baker traveled to two Nexcom stores in Virginia to observe the initiative in action. Here’s what they saw.
